Dear Paul
I have not seen this article nor profile. Having seen other Claes Sundin profile of Ju 88 C-6, it appears straight out of box, so to speak, good but not exceptional (research wise). I say this after having researched the type for some years and made own large scale drawings.
a.) Common? Yes. First A-4 indeed had straight-up tip rudders. Vertical fin was basically the same. But A-4 rudder was metal covered, whilst previous A-1/5 had this fabric covered. Perhaps you did not know that.
b.) Aerodynamic balanced rudders appeared (autumn 1941) long after A-4 entered production (the Jumo 211 J engines ruling the designation here), but VDM metal props appeared again on Ju 88 D-5 in winter 1941/1942, due to Wood props bottlenecks. W.Nr. (088)1050 appears "quite normal built" to me.
c.) No offense meant. Please leave space between in the designation Ju 88 A-4. Respecting how the designations were
most often written is respecting how things were. Changing this into Ju88A-4 as one entity had done deliberately is misleading to those who perhaps do not know better. I have said this before. We all know this, do we not?
